lib/sh/util.sh: echo_func(): display where the function was declared (using new func_loc()) instead of where echo_func() was called from. this is more intuitive when debugging, becaues the line # is where the function starts. it also helps remove the dependency on the FUNCNAME/BASH_* arrays, which would produce an inaccurate value if another function call (such as log++) intervened between the caller and echo_func().
